Abstract
Dynamics of thin layers of entangled polymers is considered theoretically using a generalization of the reptation model. It is shown that monomer-monomer excluded volume interactions suppress long-range motion of polymer chains, giving rise to an exponential increase of the longest relaxation time and the viscosity as the layer thickness is decreased. Explicit dependencies of on concentration, molecular weight, and thickness are obtained.
